Description : Search for proofs in equational logic
The OTTER sources include MACE and FormEd, described below.
OTTER is an automated theorem prover for equational logic developed
at Argonne National Laboratory.
.
OTTER's inference rules are based on resolution and paramodulation,
and it includes facilities for term rewriting, term orderings,
Knuth-Bendix completion, weighting, and strategies for directing and
restricting searches for proofs. OTTER can also be used as a symbolic
calculator and has an embedded equational programming system.
MACE is a program that searches for finite models of first-order and
equational statements developed at Argonne National Laboratory.
.
This package includes ANLDP, which calls the propositional decision
procedure at the core of MACE directly.
.
MACE serves as a complementary companion to OTTER, which
searches for refutations of the same class of statement. In
particular, if you have a first-order conjecture, OTTER will search
for a proof, and MACE will search for a counterexample from the same
input file.
Formed is a formula editor for first-order logic formulas that
lets you simplify quantified formulas by quantifier
transformation among other things.
